摘要

This invited paper describes recently reported work on the application of magnetic force microscopy (MFM) to image currents in IC conductors (1). A computer model for MFM imaging of IC currents and experimental results demonstrating the ability to determine current direction and magnitude with a resolution of (approximately) 1 mA dc and (approximately) 1 (mu)A ac are presented. The physics of MFM signal generation and applications to current imaging and measurement are described.
